CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 410,766, datedSeptember 10, 1889.

"' Application filed May 6, 1889.

To all whom it may concern:

Be it known that I, JOHN H. MOINTYRE, a citizen of the United States,residing at Rutland, in the county of Rutland and State of Vermont, haveinvented certain new and useful Improvements in the Mode of Hanging andOperating Freight-Car and other Doors; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompany- 1ngdrawings and letters of reference, thereon.

My invention consists, first, in certain novel constructions,combinations, and arrangements of parts for use in connection withfreight-cars or orther structures having doors which close from theoutside, whereby such doors can be shut into their casings flush withthe outside surface or boarding of the car or other structure, thusmaking a perfectly even continuous surface, and securing such a snug fitthat fire, rain, snow, and dirt will be prevented from having access tothe interior of the car; also, rendering the doors not liable to beinjured by coming in contact with other cars or obstructions, andwhereby, also, the doors can be swung out bodily (while remainingsuspended) and lowered upon footguides outside the boarding of the car,and then slid on their suspending-rails and along said guides until thedoorways are opened fully or to the desired extent.

In the accompanying drawings, Figure 1 is a side elevation of a portionof a freight-car, showing my invention, in this view the door beingraised, closed, and bolted orlocked. Fig. 2 is a similar view to Fig; 1,the door being unbolted or unlocked, swung out, lowered, and opened.Fig. 3 is an end view of a freight or other car, one door being open andthe other closed. Fig. 4 represents in detail a suspending-sheavehousing and a hinge of the door in front and in edge view as the sameappear when the door is swung bodily outward and lowered, so as to movein foot-guides on the car-body. Fig. 5 is a side elevation of thelock-plate with its twobolts partly broken away. Fig. 6 is a detail viewof a double crank or rocking bar for supporting the bolt-operating leverand bolts and moving the bolts in opposite directions.

Serial No. 309,744. {No model.)

In the accompanying drawings, A represents a freight-car having doorwaysa a in its sides, and B B represent doors for fitting into said doorwaysin such manner that the outer surfaces of the doors and sides of the carshall be substantially fiush with one another when the doors are closed,as indicated at B in Figs. 1 and 3, and shall stand out beyond saidsurfaces of the car when'the doors are opened, as indicated at B, Figs.2 and O 0 represent rails above the doorways a a and firmly secured tothe car at b I), thus forming suspension-tracks for the doors to rideand move upon in opening and closing; and D are L-shaped foot-guides setat proper distances apart and firmly attached to the lower frame-timbersc of the car. The rails and guides stand outside the boarding of the carin nearly the same vertical planes, as shown.

At the upper edge of each of the doors B B one, two, or more slottedhinge-plates d d are applied, and said plates are respectively formedwith a bevel bearing-surface d and a pintle-eye (1 as shown. To theseslotted plates suspension-sheave housings E, carrying, respectively, asheave or roller 6, are jointed by means of links F, fitted in the slotsof the plates at d and housings E, and connected to the hinged plates dcl and the lower curved or other suitably-shaped ends f of the housingsE by means of pivot-pintles g g, as shown. The bevel portions (1 of thehinged plates extend up far enough to form abutments and stops for thecircular abutting ends of the housings, and thereby make the jointspractically stifi in one direction when the parts are in the positionshown in Fig. 4, andthe door B is in the position shown in Figs. 2 and3. The housings E are constructed, respectively, with a sheave or rollerchamber 9 are open at one side, as indicated at g, and grooved below thechambers g as indicated at 9 so as to accommodate the sheaves or rollersa, receive the rails O C,and permit said rails to extend up into themand come in contact with the said sheaves or rollers, and also extenddown into them,and thereby form guides which positively keep thehousings on their suspension tracks.

The manner in which the sheave-housings are constructed and applied tothe rails is clearly shown in Figs. 1, 2, 3, and -l-, and by referenceto Fig. 5) it will be seen that the links 1, by assuming a horizontal.position, cause the door 13, for instance, to rise and swing inward fromits open position (shown at I in Fig. 3) to its closed position, (shownat B in Figs. 1 and 3,) and that thus the door B is caused to enter thedoorway a with its outer surface standing substantially even or flushwith the outer surface of the boarding of the car. Again, that the linksI, by being able to reassume a vertical position, allow the door by itsgravity to swing outward and downward from its closed raised position(shown at 13 in Fig. to its open and lowered position (shown at B in thesame figure,) and that when it is in this position its lower edge abutsagainst or stands within the foot-guides D, along which and upon therail 0 it can be slid longitudinally until the doorway is fully openedor to the extent desired.

The doors hung as described can be directly manipulated; but I prefer tooperate them by mechanism comprising housings E, having sheaves orrollers c, and mounted on rails (J (1 and connected to the car-doors bymeans of rods 71, jointed at one of their ends to the car-doors andbooked by their other ends to elbow-levers '2', pivoted to the saidhousings and having their long arms furnished with slidingoperating-handles j,which are pivoted and guided, as shown. \Vith thisarrangement, by pulling up a handle a door can be caused to swingoutward and downward, and by pulling down said handle said door can beraised and caused to swing inward, the rail serving as a purchase whilethe above-described movements are being made.

About midway of the height and central of the width of each of the doorsI) 1 an angular lock-plate G is provided, the same being securelyfastened to the door and comprising a bottom stop 7.: and perforatedkeeper-lug Z. At the angle of the loeleplate a round aperture is bored,and in the same is fitted a cylindrical portion on of a rocking arbor72, carrying a double-crank or rocking bar 1), as shown. To an extendedsquare endn of the arbor a an operating-lever m is fastened, said leverhaving a curvedperforated lug m on its upper edge for entering thekeeper-lug Z and receiving through its perforation a fastening-pin m, asshown.

II II arelong bolts connected, respectively, to the double-crank orrocking bar 1) and by said bar caused to move in opposite directions andenter keepers ll II in the jambs of the door-easing, as shown by dottedlines in the drawings. \Vith this arrangement, by

turning up the lever on and passing its lug on through the keeper-lug Zand inserting a pin on the bolts will be moved to and held in theirlocking positions, and by taking out the pin and turning the lever mdown against the stop 7.: the bolts will be withdrawn and the doorunlocked ready to be swung outward and downward and then slid open.

\V hat I claim is- 1. The combination, with a car or other structure,the sliding door thereof, and asuspension-track, of the slidingsuspension device comprising hinge-plate (I, provided with an abuttingand stop-extension portion for insuring a vertical position of the link,the housing E, and connectingdink I pivoted directly to the hinge-plateand to the said housing, whereby the door when closed can be made tooccupy a vertical position within the doorway while suspended on thetrack with its outer surface flush with the outersurface of the ear orstructure, and when it is to be opened can be bodily swung out and downbeyond said outer surface, so as to stand vertically and then be slidlongitudinally, substantially as described.

2. A door closing from the outside provided with a hinge-plate (Z,having a bevelsurface (F, in combination with a suspensionhousingprovided. with an abutting end fand with the link F, sul )stantially asdescribed.

3. The combination of the jointed suspension means, consisting of thehousing E, hinge-plate (I, provided with an abutting and stop-extensionportion for insuring a vertical position of the link, andconnecting-link pivoted directly to the hinge-plate and to the housing,door, car-suspspending track, and footguide, the two latter being inabout the same vertical plane, substantially as described.

-l. The combination, with the door having jointed suspension means, asdescribed, ot the housing E, an elbow-lever pivoted to said housing, aconnecting-rod attached to the door and lover, and an operating-hamlle,substantially as described.

5. The sheave-housings constructed with a chamber for a sheave or rollergrooved and open at one side to admit the rail and providcd with ahinging end, in combination with the hinge-plate provided with anabutting and stop-extension portion for insuring a vertical position ofthe link, and the link 1 pivoted to said housing and hinge-plate,substantially as described.

6. The combination, with the car provided with a suspension-track and alower guide, both in about the same vertical plane, of a door providedwith a hinging-plate, a link which is adapted to lie horizontally andstand vertically, and. a housing which is pivoted to the link and moveson the suspension-track, substantially as and for the purpose described.

In testimony whereof I hereunto allix my signature inv presence of twowitnesses.
